construction adhesive 1. high-powered,elastic after cured; 2.well-sealed one-component ; 3.polyurethane building seala construction adhesive CS-a4 is a kind of high-powered,elastic after cured,well-sealed one-component polyurethane building sealant. It reacts with air and solidifies to form a permanent hyperelastic materials. CS-A4 is in strengthened structure,widely used in bond and sealing of construction material. product performance:1.Single-component,good thixotropy,convenient construction;2.High intensity,tall flexibility,good adhesiveness;3.Good resistance to water,oil,aging;4.Solvent-free,no expand and contract after curing;5.Possible for spraying on surface. Applied range:Apply to all kinds of construct precast unit,hardware andother structural joint prepared bonding and sealing.Apply to all kinds ofexpansion joint of buildingk,deformation joint,construction joint sealing.Suitable for various types of stone flooring,ceramics sealing and decration,the same for other building walls,access panle.Construction attentions:1.Carefully check relative identifier of sealants products.2.Remove all kinds of oil and dirt,keep jointing surface cleaning&dry.3.Use relative cleaning activator handling agents or primer selectively.4.Use manual or pneumatic gun paint,repid adhesive in surface dry time.5.The best construction temperature 5-40C,RH between 65%-75%.6.Uncured CS-1001 can be removed from tool or equipment,cured can only be removedby mechanical mean.Use industrial handrub immediately if you hand or skin gum on,not solvents.
